Run batted in
A run batted in or runs batted in (RBI[1]) is a statistic in baseball and softball that credits a batter for making a play that allows a run to be scored (except in certain situations such as when an error is made on the play). For example, if the batter bats a base hit which allows a teammate on a higher base to reach home and so score a run, then the batter gets credited with an RBI.
Before the 1920 Major League Baseball season, runs batted in were not an official baseball statistic. Nevertheless, the RBI statistic was tabulated—unofficially—from 1907 through 1919 by baseball writer Ernie Lanigan, according to the Society for American Baseball Research.[2]
Common nicknames for an RBI include "ribby" (or "ribbie"), "rib", and "ribeye". The plural of "RBI" is a matter of "(very) minor controversy" for baseball fans:[3] it is usually "RBIs", in accordance with the usual practice for pluralizing initialisms in English;[4][5] however, some sources use "RBI" as the plural, on the basis that it can stand for "runs batted in".[3][4]
Criticism[edit]
The perceived significance of the RBI is displayed by the fact that it is one of the three categories that compose the triple crown. In addition, career RBIs are often cited in debates over who should be elected to the Hall of Fame. However, critics, particularly within the field of sabermetrics, argue that RBIs measure the quality of the lineup more than it does the player himself. This is because an RBI can only be credited to a player if one or more batters preceding him in the batting order have reached base (the exception to this being a home run, in which the batter is credited with driving himself in, not just those already on base).[7][8] This implies that better offensive teams —and therefore, the teams in which the most players get on base— tend to produce hitters with higher RBI totals than equivalent hitters on lesser-hitting teams.[9]
